Hightlight checkbox like YAHOO email!

Hey...I wonder how to do the HIGHTLIGHT SELECTED ROW using checkbox as well as using the "SELECT ALL" text and "CLEAR ALL" text just like yahoo email do...

I have tried to find the code but the yahoo page is just too "CLEVER" hiding its code from the user, lol....

Could anybody help me, any website refference of that code, or maybe anybody know the code....?

I just want to touch up a little bit of my system before submitting them to the the owner! Please anybody...

use javascript and css. when the row is selected use javascript to chnage the background colour style of the row, you'll need to give each row an id which you wil need to pass as a variable to the javascript function
